The fortress of Halidzor (Armenian: Հալիձորի բերդ) is along a hill overlooking the Voghji River to the north, near the town of Kapan, which is 1 kilometre (0.6 mi) southwest in the Syunik Province of Armenia.

During the 18th century, the famous Armenian military commander and liberator David Bek and his chief lieutenant and successor Mkhitar Sparapet used the site as their main headquarters as well as an administrative center for Syunik in their fight against the forces of the Ottoman Empire and the Iranians.

The defensive nature of the location gave Bek's soldiers an advantage when fighting the enemy, but the siege left the defenders of the fortress weary with little food.

After David Bek's death, the Ottoman army captured Halidzor and notified the defenders that they would take control of the fortress but leave the battalion and residents unharmed.

The church at the eastern side of Halidzor is a vaulted hall-type structure constructed from large stones in the form of rubble masonry.
